http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.htmlhttp://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.htmlT104 is 240Volt timer.
When you open the door, there should be piece of translucent plastic covering the wiring.
As long as plastic cover is in place, it is safe to touch visible timer parts.
If you have a child who might stick something into the timer, then lock timer door.
As a general rule with electrical devices, do not stand on bare ground or wet surface or lean into or touch anything metal while working on timer. Put down dry boards. Same with your circuit breaker panel.
The T104 yellow dial rotates just like a clock.
The dial has ON and OFF trippers attached to outer edge of dial.
As these trippers rotate around they move on-off lever that turns the pool pump or Load on and off.
ON tripper moves lever one direction, and OFF tripper moves same lever other direction.
The manual override lever clicks back and forth with audible sound each time tripper moves on-off lever.
Move manual override back and forth and it will turn Load on and off.
Override should snap crisp and clean.
To set timer, lift and rotate dial until current time lines up with stationary silver pointer.
Stationary silver pointer is pointed at 6:00.
